Various tweaks to support building with excessive GCC warning flags
This fixes a bunch of small issues in order to enable a clean successful build with a crazy number of GCC warning flags. A lot of these changes are covered by -Wshadow, -Wformat-security, and -Wstrict-overflow=5. Signed-off-by: Dan McGee <dan@archlinux.org>
